PHILADELPHIA — Tyson Chandler said he was “75 percent’’ entering last night’s rematch against the 76ers but a lot better than he was Sunday.

Playing with strep throat, Chandler made 75 percent never look so whole as he helped the Knicks romp past the Sixers, 110-88. In a vintage performance and taking advantage of center Andrew Bynum’s indefinite absence, Chandler rocked the rims for 14 points and six rebounds.

“It was night and day,’’ said Chandler, who started feeling his infection against Miami Friday. “It’s amazing what some fluids can do for you.’’

Point guard Raymond Felton connected with Chandler on two vicious alley-oop dunks. Felton, who finished with 16 points and eight assists, also found Chandler underneath with a beautiful bounce pass threaded through two Sixers defenders. The Felton-Chandler hookup is looking like the Felton-Amar’e Stoudemire union did two years ago.

On Sunday, the Knicks beat the Sixers despite Chandler’s ailing condition. He played 21 minutes and scored just two points. He left midway through the third quarter and did not return. He got IV fluids after the game.

“I felt terrible after the game,’’ Chandler said. “Once I got fluids, I felt better. But not being able to eat or drink and trying to get out there and play, it was bad.’’

Chandler had a debilitating flu to start the playoff series against the Heat in April that hindered his performance. Then he got sick again during the Miami opener. He said a Knicks trainer joked he had “Bosh Flu’’ — named after Miami big man Chris Bosh.

Chandler said this illness was not as severe as the one in the playoffs.

“I got kids,’’ Chandler said, explaining it off.

At least Chandler did not have to contend with Bynum. The Sixers are a different team without Bynum, who is out indefinitely with knee problems and will battle Chandler for top center in the East.

“He’s definitely going to change their team and offense,’’ Chandler said. “Now they do a lot of perimeter. They’ll probably slow it down and get him touches on the block.’’

* The Sixers were missing Jason Richardson, who sprained his ankle tripping over a courtside photographer Sunday in New York. … There were some chants for Marcus Camby, who sat out again. Woodson is waiting for Camby to get two scrimmages under his belt so he can debut Friday vs. Dallas — if there’s room in the stacked rotation.
